Policy-as-code configuration & compliance automation for hybrid infrastructure
Discover top open-source software, updated regularly with real-world adoption signals.

Simple, agentless automation for configuration, deployment, and orchestration.
Ansible automates configuration, application deployment, cloud provisioning, and network tasks using a human‑readable language, agentless SSH, and parallel execution for fast, secure IT operations.

Ansible provides a radically simple way to automate IT tasks—from configuration management and application deployment to cloud provisioning and network configuration. By leveraging existing SSH (or WinRM for Windows) connections, it eliminates the need for custom agents, enabling rapid, secure, and auditable automation.
Designed for developers, operations teams, and enterprises that value a low‑learning‑curve, declarative syntax, Ansible lets you describe infrastructure in YAML playbooks that are both machine‑ and human‑readable. Modules can be written in any dynamic language, and the platform runs tasks in parallel across thousands of nodes, supporting non‑root execution and instant onboarding of new machines.
Install Ansible via pip or native package managers on most platforms. The active community offers forums, newsletters, and a clear contribution path through the devel branch and Contributor’s Guide, ensuring continuous improvement and support.
When teams consider Ansible, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Zero‑downtime rolling application updates
Deploy new versions across load‑balanced servers without service interruption.
Cloud infrastructure provisioning
Create and configure AWS, Azure, or GCP resources consistently via playbooks.
Network device configuration
Automate switches and routers configuration using Ansible’s network modules.
Ad‑hoc task execution across fleet
Run one‑off commands on hundreds of servers in parallel for patching or diagnostics.
No, Ansible operates agentlessly over SSH (or WinRM for Windows).
Modules can be written in any dynamic language such as Python, Ruby, Bash, or PowerShell.
Install via pip, OS package managers, or from source; detailed guides are on the website.
Ansible supports Windows using WinRM, though feature parity is higher on Unix‑like systems.
